    mm: new arch_remap() hook · 4abad2ca
    Laurent Dufour authored
    Some architectures would like to be triggered when a memory area is moved
    through the mremap system call.
    This patch introduces a new arch_remap() mm hook which is placed in the
    path of mremap, and is called before the old area is unmapped (and the
    arch_unmap() hook is called).
